ListDataProvider, but you're also calling setRowCount() and
setRowData() which you don't need to do when using a ListDataProvider.
In terms of sorting, your ListHandler is configured to act on the same
list that the ListDataProvider uses, which is what I've found to work.
The trick comes when updating the list being displayed. You can't just
call ListDataProvider.setList() because there's no setList() on
ListHandler (I have no idea why not). Instead, you have to call
ListDataProvider.getList().clear;
ListDataProvider.getList().addAll(newData);
Finally, be sure to call CellTable.getColumnSortList().push(column)
when updating the data to reflect the initial sort order of the data.
I'm only just figuring all of this out myself, so if this doesn't work
or if anyone has other suggestions, please let me know.
